Looks great, I like the boot idea, I've been thinking about doing my MKVI boots over in foam, please keep us posted on your progress, I may borrow some ideas on how you build yours
Also just some quick advice on the MKV A helmet, I suggest that you add those vents to the front of the helmet before you harden it, I just borrowed the vent from one of the previous MKV A files that are running around, use it for a template as it will not line up perfectly, and then he can either use the pieces that go in each vent or leave them out and use them for air flow, otherwise he's doing great so far
